“Water” is the best thermal insulator.
Option: B
<u>Explanation</u>:
“Thermal insulators” are the materials which do not allow heat to transfer. “Water” is the substance which does not transfer heat. Hence, the “water” is the best “thermal insulator”. Water is the bad conductor of thermal heat. Water has “low thermal conductivity” than other substances, so this acts as an insulator as long as it is not traveled from one place to another. Heat is transferred when a “hot object collides” with “the cold objects”. The “thermal conductivity” of “water” is 0.6 W/m K.
Answer:
Moving them farther apart
Explanation:
One can try to change the distance between the two positive charges in such a way that it increases the distance and decreased the electric force.
It protects the nucleus and
Answer is: fatty acids of short (C4-C6) and medium (C8-C10) chain fatty acids (SCFAs and MCFAs) solubilize in intestinal fluids and are absorbed directly into the portal system.
Fatty acid with ten carbon atoms made medium chain triglycerides, that we also consume by food and get energy by breaking bonds between and oxidizing carbon atoms.
